BEHAVIOR OF DOUBLE GEONET DRAINAGE SYSTEMS

Geonets are netlike polymeric materials formed from intersecting ribs joined at their junctions and used exclusively for the in-plane drainage of liquids. The intital use of geonets has been in waste containment facilities for the drainage of liquid in leak detection systems and in primary leachate collection systems. The design of a geonet drain focuses on three considerations: adequate flow rate capability; sufficient compressive strength; and adequate shear stability. The article describes aspects of the system and its use. Flow rate behavior is described, as well as compressive strength behavior and shear stability. The real benefit of the double geonet concept was found to be when a geotextile with soil above is used. It is noted that the double geonet scheme for increased geonet fow rate capability is a valid concept as long as the geonets do not reorient themselves and fold into one another.
